26899	Document why RawSQL requires parameters	David Wolever	petedmarsh	"The `params` argument to `RawSQL` isn't optional so an empty tuple must be provided if no arguments are needed:

{{{
>>> RawSQL(""some_column"")
...
TypeError: __init__() takes at least 3 arguments (2 given)
}}}

It seems reasonable to make `params=()` the default: `RawSQL(sql, params=(), output_field=None)`, or possibly `params=None` and `self.params = params if params is not None else ()`.
